| Galileo color image of the Moon showing the western hemisphere and Orientale Basin. The Orientale Basin is just left of the center of the image, at 20 S, 265 E, and has a diameter of about 1000 km. The right side of the image is on the Moon's near side and left on the far side. The dark area at upper right is Oceanus Procellarum, below it is the circular Mare Humorum. The dark region at lower left is the South-Pole-Aitken basin. The image was produced from three exposures, through violet, red, and near-IR filters, from roughly 560,000 km. (Galileo, P-37329) |
